THE INDUSTRIAL WORLD.

Millions Of washboards are made
and sold annually in this country. It
Ia estimated that not less than 1900, 900
Of them are sold every year between
the Allegheny mountains and the Mis-
souri, river.
e. Cooper, of Santa Barbara, has
proved that olive culture can be made
TO pay in California. He has grove
Of six thousand trees, which yearly
yield fifty thousand bottles Of excellent
oil, which he sells for one dollar a bottle.
The Chevalier van Flewyck, of
Louvain, has just perfected, after
thirty-eight years of labor, machine
for recording all music extemporized
upon the piano. His invention is
worked by means of electricity, and he
has been assisted in the mechanical de-
tails by M. Kermis, an engineer of
Brussels.
"A tunnel is projected, to be bored
under Gray's Peak, in the Rocky Noun
tains. 1t will be placed 4,441 feet be-
low the summit of the mountain, will
be $4,000 feet long, and will give direct
communication between the valleys in
the Atlantic Slope and those of the Pa
cific side, with shortening of some
300 miles in the transmontane dis
tance.-San Francisco Chronicle.
In 1890 nine-tenths of the popula-
ton of Massachusetts were engaged in
agriculture, while in 1880 only one
eighth were occupied with that class Of
work. In the great States OF New York
and Pennsylvania four-fifths of the peo-
pie are not engaged in agriculture, and
in Illinois, the greatest agricultural
State in the Union, less than one-half
of the population is occupied with
farming. Boston Herald.
The difficulty of sighting rifles in
the dark in warfare has been ingeniously
overcome by the use of luminous paint.
A small luminous bead is clipped on to
the rifle over the foresight. and another
over the rear sight when used at night
in reply to an enemy's fire, forming
two luminous sights. The British War
Office authorities have had some of
these sights under trial for the past six
months and have now given their first
order for them.
"A new method of manufacturing
car-wheels has been tested at Wilkes
barre, Pa. with satisfactory results.
BY the old method three men could
make only eighteen wheels per day of
twelve hours. BY the new process the
same number of men can turn out a
perfect wheel every minute, or 72O per
day. One of the principal features of
the new method is the use of a steel
core, instead of one of sand, in casting
the wheel. The core is removed by
knocking out center key, leaving the
hole perfectly true and ready to put
upon the axle at once, without dressing
or boring. Pittsburgh Post.
-Shoe-pegs require 100000 cords of
timber annually in their manufacture;
matches, 100000; lasts and boot trees,
500,0O All this is of the most superior
quality, straight grained, and clear OF
knots and gnarls. To raise the tele-
graph poles of the country required
100000 trees, and 100000 more are re-
quired for annual repair. The railway
ties of the country annually consume
$4,000 acres of timber at least thirty
years old, and the fencing of railways
represents $4,000, 900, and the annual
repair $15,000,000. These are but a
moiety of what is required of our forest
supply. The burning of brick alone
requires 100000 cords Of wood an
nually.-N. y Tribune.
